The MacBook is a great tool for yearbook design and creation. I have learned that the best way to get familiar with Mac computers is to use them and discover things on your own. They can do everything Dell computers can do, but it may be called something different or have a different format. The MacBook also has IPhoto which allows you to make slideshows quick and easy and PhotoBooth which allows you to take quick pictures to publish.
Managing computers in my classroom is fairly easy because I have enough for most classes. My students are assigned a computer at the beginning of the year and throughout the year when I feel the need for a seat change.
